Specification of Letters Patent.v

rammed Oct..9,.,1 906.

Application filed OctoberZ. 1905. *Serial No. 280,962.

To all whom it may concern.-

Beit known that I, EDWARD JAMES RIoH- MOND', a citizen of the United'States, residing at Lamar, in the county of Barton and State of Missouri, have invented a new and useful Hay-Press Feeder, of which the following is a specification.

This invention relates to feeders for haypresses and it is designed as an improvement of the device of thisclass for which Letters Patent of the United States No. 779,736 were issued to myself on the th day of January, 1905.

In the construction shown and claimed in the patent aforesaid it was found that the tamping member would sometimes drop in the-press-box at a time when the latter was empty. The object ofthe present invention is to overcome this disadvantage and to simplify and improve the construction and operation of this class of devices.

With these and other ends in view, which will readily appear'as the natureof the-invention is better understood, the invention consists in an improved independent lock and trip mech'anism'to be used in connection with the tamping member. i

The invention further consists in the improved construction and novel arrangement and combination of parts, which will behereinafter fully described, and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the.

invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but that changes, alterations, and modifications within the scope of the invention may be resorted to when desired.

In said drawings, Figure 1 is a side elevation of a portion of a hayress embodying the invention. Fig. 2 is a etail view showing the parts of the invention in a different position.

Corresponding parts in the figures are indicated b like characters of reference.

1 designates the hopper or receiving-chamber of a press.

2 is the plunger, having the rod 3, which is in practice connected with operating mechanism. (Not shown.)

' 4 is a retracting spring whereby the plunger is retracted to the position shown in upporting means, as uprights 5 and brackets 6, are provided for a cable-pulley 7', over which is guided the cable 8, connected with guides 9, carrying a weight which constitutes a tampin member 10. The cable 8 is guided over pulI eys 1 1, 12, and 13 to a fixed point of attachment, such as a bracket 14. The pulley 13, which is engaged by a loop or bight of the cable, is connected by a strap 14 with a slide 15, movable between flanges 16 of a guide-plate having ears or lugs 17 apertured' for the passage of bolts 18, whereby it is clamped and secured upon one side of the sill 19 of the press. Guiding means are provided upon the slide fora slidingv bar 20, the front end of which is connected, as by a bar 21*, with the plunger-rod. The bar is provided with a shoulder 21, adapted to be engaged by an upwardlyextending lug 22 of a pawl 23, which is pivoted upon thebolt 24, which connects the strap 14 with the slide 15. The pawl 23 also has a downwardly-extending beveled lug 25, adapted to engage a beveled shoulder 26, formed near the front end of the lower flange 16 of the guide-plate. The pawl 23 is also providedwlth a forward-1v extending lug 27, adapted to be engaged by a latch lever 28, which may be pivotally whereby the flanged guide-plate is secured in position, said latch-lever beingconnect-ed by a retracting-spring 29with a fixed point, said retracting-spring serving to keep the latch member in engagement with the lug 27 of the pawl 23, as indicated in Fig. 2 of the drawings, until released by means which will now be described.

Hingedly mounted within the hopper 1, near the upper edge of the latter, is a tripplate 30, which is connected by a rod 31 with one end of a lever 32, which is pivoted upon one of the uprights 5 and the opposite end of which is connected by a rod 33 with one arm of a suitably-supported bell'crank lever 34, the other arm of which is connected, as by a link or rod 35, with the latch member 28.

In Fig. 1 of the drawings the plunger has been shown in retracted position. When it advances into the press, the slide 20 will be mounted upon one of the lower bolts 18,.

carried along by the connecting member 21, and the shoulder 21 of said slide engaging the lug 22 of the pawl 23 will carry the latter and 26, after which the latch member actuated by the spring 29 will be restored to its former position, thus locking the pawl in the position described. While the parts are in this position the attendant will place a charge of hay or material to be compressed into the hopper, and said material dropped upon the tripplate 30 will disengage the latch member 28 from the pawl 23, so that when the plunger is retracted by the spring 4 the slide 15 will be free to return, thus permitting the tamping member to drop into the hopper, where the hay will thus be primarily compressed. In the event, however, of no charge being placed in the hopper the trip-plate 30 will not be actuated, and the latch member 28 will consequently remain in engagement with the pawl 23, retaining the latter and the parts connected therewith in a locked position and preventing the tamping member from dropping.

While the present invention, which includes the locking and the trip mechanism, has been described as being applied to a press of the character formerly patented by myself, I'desire it to be understood that this mechanism may be applied to other presses of a similar character.

. Having thus described the invention, what is claimed is- 1. In a press, a tamping member, a plunger, a primary slide having means connected therewith for elevating the tamping member, an auxiliary slide, means for connecting the primary and the auxiliary slides to move in unison, and means for locking the auxiliary slide in an advanced position to thereby retain the tamping member in an elevated position.

2. A press having a hopper, a tamping member movable vertically in said hopper, a plunger, means for reciprocating the latter, a slide having means connected therewith for elevating the tamping member when said slide advances, an independently-movable slide connected with the plunger, a pawl pivotally connected with the first slide and adapted to engage a shoulder upon the second slide thereby causing the slides and related parts to advance in unison, stop means to engage said pawl to retain the slide connected therewith in advanced position, and a spring-actuated latch member adapted to en'- gage said pawl to retain it in locked position.

3. A press having a tamping member, means for elevating said tamping member, means including a pawl and a spring-actuated latch member for retaining the tamping member in an elevated position, and a tripplate connected with said spring-actuated latch member and adapted to actuate the latter against the tension of the spring when a weight is placed upon said trip-plate.

4. In a press, a hopper, a tamping member movable vertically therein, a trip plate hinged to the hopper, means for elevating the tamping member, means including a pawl and a spring-actuated latch member for retaining the tamping member in a raised position, and connecting means between the spring-actuated latch member and the trip- ,plate whereby a charge placed upon the latter shall operate to release the latch member from the pawl thereby permitting the tamping member to drop.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

EDWARD JAMES RICHMOND.
